Lower your treatment cost and hit your effluent limits
We make the chemicals and nutrients that treat industrial wastewater — and we prove them on your own effluent before you commit. For textile mills, municipal plants, farming operations, and food processing.
Remove suspended solids and color
Chemical treatment, matched to your stream by jar testing in our lab and on your site.
-
Coagulants
Destabilize suspended solids so they form flocs that settle out of the water.
-
Flocculants
Grow the particles so they settle faster. Cationic and anionic polymers.
-
Decoloring agents
Remove color from highly colored streams — textile, printing, and ink wastewater.
-
Antifoam
Control foam in aeration basins and tanks where it interferes with treatment and monitoring.
Biological treatment
Biobooster™ — more efficient degradation, less sludge
Cultiva's proprietary nutrient technology, backed by more than five years of in-house R&D. It is a micronutrient feed for the decomposer bacteria: it supplies the trace nutrition activated sludge needs to grow dense, healthy, well-settling floc, and it improves the resilience of that biomass to load swings.
A clear, colourless liquid at pH 5.0–6.5, supplied in 120 kg drums. The maintenance dose is 1 to 10 ppm and it is set during the trial, on your plant — dosage varies with the conditions in a works, so nobody can pick it off a datasheet.
- Aerobic activated sludge and anaerobic stages — one product across both
- MBBR and clarifier-based systems
- Textile, paper, food and other industrial WWTPs
- Liquid dosing, no capital equipment
From healthier bacteria to a cleaner, steadier outlet
Fix the biology and everything downstream gets easier. Biobooster works on the bacteria, not on the symptoms.
-
Feed the bacteria
Trace nutrition raises the growth rate and the resilience of the decomposer biomass.
-
Denser, heavier floc
The biomass builds thicker flocs that settle fast and do not float when the basin is disturbed.
-
Less carryover
Solids stay in the clarifier instead of escaping downstream, so TSS falls.
-
Lower load, and stability
Downstream COD drops and the process holds steady through load swings.
What it has done at plant scale
Four trials, dated, with the industry named. The customers are not named, at their request. Five plants run Biobooster today — sugar, textile dyeing and starch.
-
2025Sugar refinery
18.5%
lower COD at the final outlet
Before 677 ppm After 552 ppm Two weeks on Biobooster measured against the previous four and a half months, with a two-sample t-test: p = 0.001 for the final outlet, 677 to 552 ppm. The feed load into the first aeration basin over the two periods was statistically unchanged (p = 0.79), which is what makes the comparison worth reading.
-
2020Textile dyeing — nylon and polyester
50–70%
sludge confluence at 100x magnification, up from 30–40%
Before 30–40% After 50–70% The settled sludge held a sharp interface and did not re-suspend when disturbed, and clarifier COD came down to 67 mg/L on the final sampling day. Field scale, 10 L/day into the aeration basin, over nine days.
-
2024Beverage bottling — treatability test
89%
average COD removal in aeration, against 71% for the existing process
Existing process 71% With Biobooster 89% Wastewater and activated sludge from the plant, aerated in the lab to match its retention time and air supply, against the existing process on the same wastewater over four days, 18–21 March 2024. Biobooster removed more COD on each of the four days.
-
2023Milk processing — our own bench
about 41%
lower COD than the raw inlet
Raw inlet roughly 1,591 ppm Treated roughly 933 ppm We aerated milk-processing wastewater with Biobooster for six days and ran the cycle four times over. The figures are a four-cycle average, and treated COD came out lower on all four runs.
What happened at those plants is not a specification: actual results depend on each plant's wastewater and its conditions, which is why every engagement starts with a treatability test on yours.
Technical support is part of the product
Jar testing, process and cost evaluation, and field support through optimization.
-
Jar test
Your effluent, our bench — coagulant and dose selection you can watch settle.
-
Plant evaluation
Process and cost review of your existing system against what it could run at.
-
Optimization
Dosing and field support until the numbers hold — and after.
What a jar test measures, and how to read the dose curve it gives you: How a jar test works, and what it tells you about your effluent.
The free jar test
Six beakers, one afternoon, one answer
The diagram is a schematic, not a photograph of our bench. It is what the test looks like: the same effluent in every jar, a different coagulant dose in each, and half an hour of watching them settle. The one that clears fastest and leaves the sharpest interface is the dose we would run on your plant.
Bring us five litres of your own effluent and we do this for nothing. You get the dose, the chemistry and what it costs per cubic metre — and if nothing we make helps, we tell you that instead.
- Your effluent, not a synthetic sample
- Coagulant, flocculant and dose chosen against what you already run
- A number you can check against your own jar, on your own bench
